redirect traffic based on destination port to another interface

[Rudy Setiawan]

Hi,

I am trying to do a traffic redirection based on destination port to
another interface/gateway.
Currently, I have a freebsd box that does simple NAT and an Internet connection.
I am planning to install another internet connection and use the same
box to do some traffic redirection.


INTERNET1 -------- freebsd box ------- INTERNET2
                                 |
                                 |
                       Local Area Network

LAN = 192.168.10.0/24 with interface em0
INTERNET1-GW = x.x.x.1 with em1
INTERNET2-GW = y.y.y.1 with rl0

My goal is to redirect any ssh traffic to INTERNET2-GW and I assume
that if it can be redirected through INTERNET2-GW then the packets
return will go through INTERNET2-GW also.

Is it possible to do that way with ipfw or natd?

Thank you

Regards,
Rudy
